Overall I can see the overall health of my business with quickbooks. I can track my expenses, sales, inventories, financial reports and other vital information for intelligent decision making. The thing I like most about Quickbooks is its completeness. For a small to medium sized business one gets to have a user friendly accounting and inventory system all rolled into one. Add to that its customizable reports suited to ones needed data. Some of these reports which are very vital to a business owner are Daily/Weekly/Monthly and even Annual Sales Report, Inventory related reports, Expenses Reports, Accounts Parables and Receivables, Banking and many more.
